Edit it appears you have to adjust text from the menu prior to typing it. Prefer having that option out in a toolbar.
You can: open the tool settings panel (View-->Panels-->Tool Settings
Did not experiment too long before the program crashed,
That is troublesome. In my experience PhotoLine is very, very stable, and almost never crashes - unless there is a bug. The devs squash those type of critical bugs the next beta version.
At the moment it seems needlessly complex, but that probably relates to the vector aspects of the program.
To say I found the manual on this confusing is being generous.
PhotoLine's functionality goes quite deep (even surpassing Photoshop in some regards), but you've discovered its Achilles' heel: almost nothing exists in regards to tutorials, YouTube presence, etc. The documentation is rather spartan.
And the default GUI setup is rather awkward in my opinion.
Interestingly enough PL exists nearly as long as Photoshop. It began its life on the Atari ST
PhotoLine is an odd outlier in the market. It does things no other image editor does, yet is hardly known about. It doesn't pull any punches, and has rough edges. Documentation is scarce, and tutorials almost non-existent. But for the more advanced user a real workhorse.
I've been an experienced Photoshop user since the late nineties, but nowadays I hardly touch Photoshop anymore - only for certain conversions (for work) and the singular feature here and there. Otherwise I tend to stick to a combo of PhotoLine and Krita and some plugins, as well as InDesign. Affinity Photo, Publisher and Designer are installed on my machine as well, but I hardly touch those. Too many core workflow issues and paper cuts.
Although I understand that many users like Affinity. Serif did a great job on marketing - although their claim that "Affinity is a professional platform for professionals" is beginning to bite them in the behind after experienced users have been asking for fundamental functionality for years and years without seemingly much happening.
I do realize that I am an outlier myself as a user ;-)
